The first is to save. The so-called "preservation" is the abbreviation of "intentional cultivation". Zhu believes that everyone has innate goodness, but at the same time they have temperament bias and material desire. Therefore, we should use the effort of "saving" to promote goodness and invent our initial heart. However, people's "heart" is mixed with material desires and righteousness, so Zhu believes that "nurturing and nurturing" only needs to restrain this kind of heart and make it content with righteousness. One day, check. "Province" is introspection, and "inspection" is procuratorial. "Introspection" means to conduct self-reflection and inspection frequently. Zhu believes that if a person wants to improve his moral cultivation, he should "look at it from time to time". This view of Zhu shows that in moral education, he not only emphasizes preventing delay, but also attaches importance to correcting future mistakes. Finish it in one day. Zhu attaches great importance to "practice". What he said is "practice", which requires putting the ethical knowledge he has learned into his own practical actions and transforming it into moral behavior. These views of Zhu involve moral education issues such as the transformation of moral knowledge into moral action, moral action being guided by moral knowledge, and whether moral knowledge is correct or not. Zhu has always advocated that the content of education should be holistic, systematic and gradual. He believes that primary school is the foundation, and it is more difficult to make up if the foundation is not solid. Therefore, primary schools should teach them the habit of sweeping, coping, advancing and retreating, shooting books with ceremony and music, and gradually cultivate their virtue from practical practice. Instead, when he grows up and enters the university, he will be taught how to do the work of "learning knowledge" and "poor management", emphasizing the road of "self-cultivation, keeping the family in order, governing the country and leveling the world" and ending in perfection. So he paid special attention to the content of primary education. He attaches great importance to the implementation of the principles from the simple to the deep, from the simple to the complex and from the bottom up in students' ideological education. Ideological and moral education in primary schools and universities should be integrated. Primary school is the foundation of university, and university is the expansion and exploration of primary school. Although the degree is different, the content is the same. It is both gradual and continuous, so that the effect of education will be significantly improved. Pursuing supreme nature is the cultivation goal of Zhu Cheng's Neo-Confucianism. To achieve this goal, on the one hand, we should reflect on ourselves, cultivate our mind and maintain a good mental state; On the other hand, we should also seek outside, study hard and recognize objective things. Zhu's own knowledge lies in "the practice of pulling the bow against the facts." "So when he teaches students, he also starts with' poverty' and' perseverance'." "Poor management" means poor supervision, serving the father and the younger brother, so the poor management advocated by him is divided into two aspects: one is poor management from books; The second is to understand all abstract things inside and outside the book. However, in his view, poverty is only the completion of "erudition", "deliberation", "interrogation" and "discrimination", which is not enough to understand the natural causes of things. Further practice is needed to complete the work of "perseverance" and achieve the purpose of education. The so-called "knowledge without action, poor management before, no settlement, only the cost of giving lectures." Therefore, he believes that "poverty" and "perseverance" must be combined and inseparable. He attaches great importance to the combination of knowledge and practice, which has positive significance and is worth learning from today's school moral education. Practice is a traditional virtue of China. China people are led by virtue, supplemented by talent. They would rather have virtue without talent than talent without virtue. " Talent without virtue, the bigger, the more powerful. "This is a matter of knowing and doing. Today we teach to educate people and study to be human. Generally speaking, Zhu's teaching thoughts are very rich, and some basic problems of teaching principles are touched upon in the teaching process, such as the automaticity of learning, learning and thinking, learning and learning, learning and behavior, teaching and learning, learning and agreement, etc. It also involves purpose, enthusiasm, good start, consolidation, ability, practicality, universality, professionalism and so on. He summarized, sorted out, summarized and reformed the teaching experience and theory accumulated for a long time in ancient China, making it systematic. Many of them are thought-provoking insights and are worth learning.
